DAVID NICKEL AND CHARLES ZATTAN, OF MORRIS, ASSIGNORS TO THE OHIO BUTT COMPANY, OF CHICAGO, ILLINOIS.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 359,226, dated March 8, 1887. Application filed May 7, 1886. Serial No. 201,473. (No model.)

To LZZ whom, 'it may concern:

Be it known that we, DAVID NICKEL and CHARLEs ZATTAN, citizens of the Uni ted States, residing at Morris, in the county of Grundy and State of Illinois, have invented certain new and useful Improvements in Door-Hangers; and we do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to letters or ligures of reference marked thereon, which form a part of this specication.

Figure l of the drawings is a representation of a front elevation. Fig. 2 is an elevation, partly in section, of the rider and brackets. Fig. 3 is an end elevation. Figs. A and 5 are detail views.

This invention relates to improvements in door-hangers; and it consists in the construetion and novel arrangement and adaptation of devices, as will be hereinafter more fully set forth and claimed.

Referring by letter to the accompanying drawings, A indicates the tracks, which are suitably arranged above the door, as shown, to support the trucks, as will be presently eX- plained. These track-rails are arranged parallel and upon a horizontal plane.

B B indicate the rollers of the trucks, which are connected in pairs by a fixed axle, E, having an external circumferential curved groove to receive the under bearing-face of the riderbar D, and the rollers have annular tapering flanges on the adjacent edges of their periphery, so as to pass on the inner sides of the trackrails, and thereby prevent the same from lateral displacement.

F F indicate the doors, which may be of any ordinary or approved form, and G indicate brackets, which are secured toV the upper horizontal edges thereof. These brackets are provided in their vertical branch with a vertically-elongated slot, H, for the passage rof the ends of the rider-bars; and the said slots are sufficiently long to permit vertical movement of the rider-bar therein and a consequent adjustment of the doors. We attach importance to the fact that these brackets are slotted, as it will be seen by such construction that lateral deviations of the riderbar may be prevented and the said bar allowed to be vertically adjusted. Below the slots in the said brackets is a lateral lug, K, having a vertical aperture for the passage of a threaded bolt, J. To the upper ends of these bolts are secured the bearing-blocks I for the ends of the rider-bar, as shown. These rods may be moved up and down in the lug-bearings of the brackets by means of the nuts a, carrying with them the bearing-blocks I, consequently adjusting the horizontal position of the riderbar and the doors hanging therefrom. The rider-bar is rounded on its under or engaging side, and bears upon the axles of the trucks,

the trucks in turn having their bearing upon the track-rails. This rider-bar is also provided With stops M on its under side, which may be made adjustable longitudinally with relation to the said bar.

The operation is as follows: The track-rails being properly arranged above the door and the brackets secured to the upper horizontal edges of the latter, the trucks are placed upon the said track. The rider-bar is then passed through the slots of the brackets and bearingblocks I and secured to the latter. The riderbar is then brought down upon the truckaxles and the force of its bearing` thereon adjusted by means of the threaded bolts and nuts supported by the integral lugs K.

Having described this invention, what we claim isf- The bracket for rolling doors, having its vertical portion provided with the transverse slot II and the integral lug-bearing K having a vertical aperture, in combination with the threaded rod passing through the said aperture and the movable bearing adapted to receive a rider-bar and secured to the upper end of the said rod, substantially as specified.

In testimony whereof we atti-x our signatures in presence of two witnesses.

DAVID NICKEL. CHARLES ZATTAN.
